Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a reaping section that raises and reaps planted stem culms, which is swingable up and down at the front of the machine body, and which ties the reaped stem culms to this reaping section. A tying device is installed to transport the bundled stem culms, and a lifting device is provided which transports the bundled stem culms in a sideways position to the rear and upper side.The lower rear portion of the lifting device receives and loads the stem culm bundles dropped from this device. The present invention also relates to a reaping and tying machine with a reaping device that is provided with a retrieving section that can be dumped around the rear fulcrum.

[Conventional technology]

In this type of reaping and tying machine with a collecting device, in order to facilitate the drive structure of each device, the tying device and the lifting and conveying device are provided in the reaping section provided at the front of the machine body to form an integrated unit. Therefore, when it is attempted to adjust the cutting height of the planted stem culm by swinging the reaping section up and down, the bundling device and the lifting and conveying device are also raised and lowered together.

[Problem that the invention seeks to solve]

However, when the tying device and the lifting and conveying device are integrally provided in the reaping section as described above, the following disadvantages occur.

In other words, since the lifting and conveying device conveys the stem culm bundle backward and upward and discharges it onto the collecting section, it is tilted backwards and installed high above, but the angle of inclination is such that it does not allow the reaping section to be used during work. Since the height is set according to the mowing height, if the mowing section is raised higher than that, the lifting and conveying device will be tilted more deeply backward. Therefore, even if the reaping operation is interrupted or finished and the reaping section is raised, the reaping section can be moved to a designated location and dumped, and the loaded stem culm bundles are released, it is difficult to lift and transport the reaping section at a deep slope to the rear. The front end of the collection section must not come into contact with the rear side of the device.

With conventional reaping and binding machines equipped with a collection device, contact was avoided by lowering the front end of the collection section to the rear and shortening the front and rear ends in consideration of this point. The space available for loading became smaller, and the amount of stem and culm bundles that could be loaded was also restricted.

The present invention was devised in view of these circumstances, and its purpose is to expand the placement space for stem culm bundles while avoiding contact between the lifting and conveying device and the recovery section during dumping. The purpose is to be able to load more stem and culm bundles.

[Means for solving problems]

A characteristic configuration of the present invention is that the lifting and conveying device includes:
The device is configured to be able to swing back and forth around a drive shaft at its lower end, and the lifting and conveying device is configured to swing forward relative to the reaping section in conjunction with the rise of the reaping section. There is, and its actions and effects are as follows.

[Effect]

In other words, when the reaping section is raised, the lifting and conveying device swings forward relative to the reaping section around the drive shaft at its lower end. Even if the front end of the section is extended forward, contact with the lifting and conveying device can be avoided.

〔Effect of the invention〕

As a result, while avoiding contact with the lifting and conveying device when dumping the collecting section, the loading space for stem culm bundles in the collecting section can be expanded forward, making it possible to load more stem culm bundles. Ta.

The circumferential speed of the cutting blade 9B is set to about three times the circumferential speed of the supply blade 9A, and on the side of the supply blade 9A, a scraping disk 9C having an uneven outer periphery is arranged in parallel. . Then, while feeding the grain stem, which has been conveyed in a sideways position by belts 6A and 6B with protrusions, to the overlapping part at the rear and upper part with a supply blade 9A having a slow circumferential speed, a cutting blade 9B having a fast circumferential speed is used. It is cut and trimmed at the base end of the stock.

Next, the drive structure of the rotary cutter 9 will be explained.

As shown in FIG. 3, a drive chain sprocket 10a is fixed to the left outer end corresponding to the stock side of the drive shaft 10 which is interlocked and connected to the driving part of the machine body, and the shaft 11A of the supply blade 9A and the cutting blade 9B are connected to each other. The first and second chain sprockets 12 are attached to the end of the shaft 11B on the stock side.

A series of chains 13 are wound around 0A and first, second, and third chain sprockets 12A, 12B, and 12C, and the rotational power transmitted from the drive shaft 10 is supplied to the blade 9A, the cutting blade 9B, and the belt with protrusions. 6B
The information is branched and transmitted to each of them. The power transmitted to the belt with protrusions 6B on the stock side is transmitted to the belt with protrusions 6A on the tip side via the lower connecting shaft 6a.

A binding device B is disposed behind the ends of the protruding belts 6A, 6B, and the grain culms that have been sent in a sideways posture are scooped in by the packer arm 8, converged and tied at the same time, and the grain culm bundles are tied. Release tool 14
Use to release it backwards.

The discharge device 14 is a blade-shaped device that rotates around the left and right horizontal axis _P2 , and its operating portion faces the grain culm supply port 15 of the clamping and conveying device C.

As already shown in FIG. 1, the clamping and conveying device C is provided with a chain case 16 that is high upwardly and slightly tilted backwards, and has a drive sprocket 17 at the lower end that is pivotally supported within the chain case 16 and a drive bracket 17 at the upper end that is pivotally supported within the chain case 16. The chain 1 with protrusions extends over the driven sprocket 18.
9 is wound around the chain case 16, and a clamping rail 20 is provided along the chain 19 with protrusions exposed to the front side from the chain case 16.

Further, a counter shaft 39 serving as a swinging fulcrum of the reaping section A and a drive shaft 17a of the drive bracket 17
In addition, as shown in FIG.
A letter-shaped arm 40 is fixed, and the lower end of this arm 40 is pivotally connected to the tip of a swing link 41 provided on the body side. In other words, a scalene quadruple link mechanism is formed that connects the counter shaft 39, the drive shaft 17a, the pivot point of the arm 40 and the swing link 41, and the support point of the swing link 41. Even if the drive shaft 17a moves downward at the same time as the reaping section A swings and rises, the rearward inclination angle of the clamping and conveying device C is kept substantially constant. In other words, in conjunction with the rise of the reaping section A, the clamping and conveying device C is swung forward relative to the reaping section A around the drive shaft 17a, and in conjunction with the descent of the reaping section A, it is rotated relative to the reaping section A. It is starting to swing backwards.

Furthermore, the shaft 21 of the driven sprocket 18 is extended outside the chain case 16, and a rotary tool 22 for raising and discharging grain culms is attached to the end on the ear tip side, and a rotary tool 22 is attached to the shaft 21 integrally with the shaft 21 on the stock side. A large-diameter rotating shaft 23 that is rotationally driven is fitted. Further, a receiving part E is provided at the rear of the upper end of the clamping and conveying device C, in other words, at the rear of the terminal end, for once receiving the grain culm bundle discharged from the device C in a sideways posture, and then releasing it all at once to the collecting section D. be.

A counter 3 is provided at the bottom of the clamping and conveying device C.
5 is provided, and the sensor link S of the counter 35 faces the upper side of the conveyance route R so as to come into contact with the grain culm bundles being conveyed. or,
A calculation device (not shown) for receiving and accumulating the detection signals of the counter 35 is provided in the control section 1, and a display device 36 for displaying the results numerically is provided in the control panel 1a of the control section 1. It is arranged so that the grain bundles conveyed to D can be counted sequentially. Furthermore, in addition to the display device 36, the control panel 1a includes a reset button 37 for resetting the arithmetic unit and returning the numerical value on the display device 36 to 0, and a button that sounds when the numerical value on the display device 36 matches a set value. A buzzer BZ is provided. Therefore, collection department D
If the reset button 37 is pressed every time the upper grain culm bundle is released to set the value to 0, the buzzer BZ will always sound every time the number of collected grain culm bundles loaded on the collecting section D reaches a predetermined amount. This allows the quantity of grain bundles to be kept constant at the time of release.

The grain culm bundle supplied to the grain culm supply port 15 is conveyed upward and rearward in a sideways posture while being held by a protruding chain 19 and a clamping rail 20, and when it reaches the end, a rotating tool 22 and a rotating shaft 23 are moved. After climbing over it and once falling into the receiving part E and taking a sideways posture, it is dropped and released to the collecting part D below. In addition, when the grain culm bundle reaches the terminal end of the clamping and conveying device C, the rotary tool 22 scrapes up the drooping tips of the grain culm bundle to adjust the release posture of the grain culm bundle, and removes the grain culm that has fallen into the receiving part E. This is to prevent the bundle from falling sideways. Additionally, if several grain culms that have come loose from the grain culm bundle remain on the conveyance path and are caught in the following grain culm bundle when the grain culm bundle falls to the receiving part E, the grain culm bundle is not received. When it is dropped and released from the stopper E, it causes a large disturbance in the release posture. Therefore, by providing the rotating shaft 23 on the stock side, the grain culms that are separated when the grain culm bundle is dropped and released to the receiving part E are hooked onto the rotating shaft 23, and the rotating shaft is transmitted through friction. The rotational force of 23, the weight of the grain culm bundle, and the elastic restoring force are used to pull the grain upward and assist the grain culm bundle to escape from the conveyance path, thereby preventing the grain culm bundle from being caught by subsequent grain culm bundles.

The receiving portion E is provided with a receiving plate 24 as a receiving member, which is vertically swingable around the left and right horizontal axes, at the rear of the terminal end of the holding and conveying device C, and the receiving plate 24 is secured by a locking device 29. In other words, the receiving position is fixed in a horizontal position and can receive the grain bundle dropped and released from the clamping and conveying device C, and the state in which the locking device 29 is released and the receiving plate 24 can be vertically swung. The receiving plate 24 swings downward due to the weight of the grain culm bundle, and is naturally switched to a discharge position in which the grain culm bundle can be dropped and discharged. The locking device 29 will be described in detail. An L-shaped link 25 is rotatably attached to the side wall of the chain case 16, a rod 26 is pivotally connected to the tip of one piece, and a pin 25a is connected to the tip of the other piece. is formed and is brought into contact with the tip portion of the arcuate link 27 that swings integrally with the receiving plate 24. Further, a first contact link 28, which is an operating tool for releasing the lock device 29, is pivotally mounted to a side wall located below the L-shaped link 25 so as to be able to swing up and down.
The tip thereof protrudes into the conveyance path R of the clamping and conveying device C, and the lower end of the rod 26 is pivotally connected.

In the figure, reference numeral 30 denotes a spring for returning the L-shaped link 25 and the first contact link 28 to their initial states and bringing the locking device 29 into a state in which it can be biased to lock.

To explain the return mechanism 31 that swings the receiving plate 24 upward to return it to the receiving position, a second contact link 32 as a return operating tool is rotatably pivoted to the upper side wall of the chain case 16. , one end of which protrudes into the conveyance path R of the clamping and conveying device C located on the lower side of the conveyance side of the first contact link 28, and the other end and the arcuate link 27
are connected via a small rod 33.

Next, the operation of the receiving portion E will be specifically explained based on the above configuration.

In a state where the grain culm bundle is received on the receiving plate 24 fixed in a horizontal position, the following grain culm bundle is moved to the first contact link 2 in the path R of the clamping and conveying device C.
8, the L-shaped link 25 rotates in conjunction with the swinging movement onto the first contact link 28, and
The abutment between the abutment pin 25a and the arcuate link 27 is released, in other words, the locking device 29 is released and the receiving plate 24 becomes vertically swingable. Then, the receiving plate 24 is swung downward by the weight of the grain culm bundle to assume the release position, and the grain culm bundle is dropped and released onto the collecting section D while remaining in the horizontal position (see FIG. 4). Immediately after this, the L-shaped link 25 and the first contact link 28 are connected to the spring 3
Although the receiving plate 24 is pushed back to the initial state by 0, the receiving plate 24 remains in the ejection position. Next, when the following grain bundle in the path R contacts the second contact link 32, the small rod 32 is pushed downward in conjunction with the upward swinging of the link 32, and the arc-shaped link 27 swings downward. Then, as the arc-shaped link 27 swings downward, the receiving plate 24 swings upward and returns to the receiving position, and at the same time, the contact pin 25a and the arc-shaped link 27 come into contact with each other, and the receiving plate 24 It becomes a fixed state.

The collecting section D has its front end inserted into the vicinity of the lower end of the clamping and conveying device C to ensure sufficient loading space, and can load more grain bundles than conventional collecting sections. Also, the fulcrum P at the rear end
It is configured so that it can be dumped around it, and the loaded grain culm bundles can be lowered to the ground all at once.

As explained above, in the reaping and binding machine with a collection device, the clamping and conveying device C does not swing backward even when the reaping section A is raised, so the collection section D is slightly extended to collect more grain culm bundles. Although it is designed to be able to be loaded, the structure is such that the front end of the collecting section D does not come into contact with the clamping and conveying device C when the collecting section D is dumped.

Incidentally, although reference numerals are written in the claims section for convenient comparison with the drawings, the present invention is not limited to the structure shown in the accompanying drawings.
